Colgate Optic White Overnight Teeth Whitening Pen

This is NOT my first time purchasing this product. Colgate Optic Overnight Teeth Whitening Gel Pen is MY go to when I am looking for quick, easy, and effective teeth whitening. I have tried others. None work as well as this. I am HIGHLY SATISFIED with this product and will buy it over and over again. Thanks, Colgate, and thanks WALMART for making this product available at such a TERRIFIC PRICE and for promptly delivering it to my home SAVING me BOTH TIME and MONEY!

Only on day three and already a noticeable improvement. It's super easy to use, has no taste at all, and as way cheaper than having the dentist do it.

After one treatment my teeth were whiter. After several treatments my whole mouth was whiter and brighter than they had been in years! I highly recommend Colgate Optic White. Love the product!

this product works great, I drink a lot of tea and it takes the stains off, but by morning my mouth feels really nasty from the product caking on my teeth.

The first few days I used this product, I was very impressed. My teeth looked whiter and I was satisfied. Then the product turned really sticky and felt like…..you know when you get tissue stuck to your lips taking lipstick or chapstick off? It's exactly like that. I had to brush my teeth a few times to get all that mess out of my mouth. I really had high hopes because I've lived all other Crest products I've used before.

Had a minor stain on my two front teeth. It was embarrassing. Used this whitening pen as directed for over two weeks diligently until it ran out of fluid. It barely even lightened it. I was so disappointed. Thought a big brand like Colgate would be able to back up their big claims. Don't waste your money like I did. Avoid this product. I did find something that worked instantly and was much cheaper. I won't even charge you for the information; baking soda! I used baking soda with a toothbrush and my little stain was gone! Yeah, baking soda is abrasive. Yeah, don't use it daily… But the results with baking soda far outperformed this whitening pen and I didn't need to use it for weeks or have my heart crushed. This was just something to cushion my time until I can actually afford to go to the dentist. Long story short don't buy this pen, buy baking soda.

Ineffective for me. I read and followed the instructions and saw no change in color. I practice great oral hygiene, and no, my teeth are not stained. i just wanted them whiter. I love the colgate optic toothpaste so I thought I would love this too. Lastly, I think I previously accidentally posted the whitening kit review on the optic white toothpaste review.

Honestly, it's a little bit of a pain to use, but not impossible. However I think it does less whitening than the Colgate pro with hydrogen peroxide and it's twice as much. Wanted to try it bc I'm on a big whitening comparison trend with some friends and across the board we didn't like this one except for our one wine drinker in the group. So maybe ok for those with daily drinking stains?

When I got home I opened the Box the brush was in there and no serum. I've ordered before and this has never happened. So check your box before you leave.

absolute garbage. nothing even came out clicking for 30 clicks. 40 clicks tiny tiny bit came out. wasn't even enough to do a few teeth. this is a horrible purchase
